SPECIFICATION forming part of Letters Patent No. 580,992, dated April20, 1897.

Application filed January 2l, 1897.

To @ZZ whom it may concern:

Be it known that I, EFFIE B. SPENCER, a citi- Zen of the United States,residing at the city of Ogden, in the county of W'eber and State ofUtah, have invented certain new and useful Improvements inWindow-Sashes; and I do hereby declare that the following is a full,clear, and exact description of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters of reference marked thereon.

The present invention has relation to that the window-frame on itspivotal connection; and it consists in certain details of constructionwhereby a more perfectly operating sash is obtained and when closed thewind and rain and also dirt and dust will be excluded and prevented fromentering the room or apart` ment, substantially as shown in the drawingsand hereinafter described and claimed.

Figure l of the drawings is a perspective view of the lower portion of awindow-frame with my invention applied thereto, the sash being shownclosed in full lines and open in dotted lines; Fig. 2, a detailcross-section, on. an enlarged scale, taken on line :c of Fig. l; Fig.3, a similar view taken online y y of Fig. 1; Fig. 4., a detail view inperspective of the locking-plate.

In the accompanying drawings, A represents the usual window-frame,within which is fitted a vertically-sliding frame B, and to which frameis suitably pivoted the windowsash C to swing horizontally, as shown, orvertically, as found :most preferable.

With the above construction when the sash is closed, as shown in fulllines of Fig. 1, the window may be raised by simply raising the frame Bthe same as in the ordinary sliding sashes, but should it be found moreconvenient for washing the window or for other purposes to swing thesash C around at an angle, as shown Oin dotted lines, this can be donewithout interfering with the sliding movement of the frame B, therebysecuring both the advantages of a vertically-sliding window,as in theordinary sashes,and a swinging window, thus securing in the one and theSerial No. 620,096. (No model.)

same window-frame the two features of a sliding and a swinging window.

The sash C, as previously stated, may be pivoted in any well-known andsuitable manner, any means being employed that will admit the sashhaving a swinging motion.

The sash C when in a closed position is held in such position by meansof a concavoconvex plate D, which bears with frictional contact againstthe edge of the sash, as shown in Fig. 2 of the drawings. A suitablespring a, which bears down upon the locking-plate D, forces it againstthe sash. This plate D is preferably constructed of sheet metal ofnearly the width of the sash-'molding and extending the entire distancearound the sash, so that a tight joint will be formed between the plateand sash to exclude the wind or rain and dust or dirt, as the case maybe. This plate D has upwardly-extending flanges h extending t-he entirelength thereof, and having at intervals elongated slots c, to receivethe ends of fastening-screws d, by which said plate is connected to thesliding frame B. These flanges enter grooves e in the frame, whichgrooves are of suflicient height to allow the free motion of the flangesb when the plate D is pressed up in swinging out the sash. 1

The sash C is formed convex to present a cam E to operate against theplate D by the swinging motion of the sash, which will press it upwardsufficient to admit the sash swinging out-ward, as shown in dotted linesof Fig. l.

It is notnecessary that thevplate D and its connections be attached tothe frame B, the same result being attained by applying it to the sash Cinstead of the frame, as shown in Fig. 3, and in place of the coiledspring, as shown in Fig. 2, a flat bow-spring or a spring of anysuitable form and construction may be substituted.

In Fig. 3 of the drawings I have shown a flat bow-spring, and the cam Ein place of being on the sash is shown on the frame B. These differencesdo not in any manner affect the operation of the sash,and any suchchanges as would come within ordinary mechanical through the slots, anda eam device for operating the plate, substantially as and for thepurpose set forth.

In testimony that I elaiin the above l have I5 hereunto subscribed mynaine in the presenee of two witnesses.
